Abstract: 1,189,119. Rotary absorption dynamometer. NATIONAL RESEARCH DEVELOPMENT CORP. July 13, 1967 [July 13, 1966], No. 31558/66. Heading G1W. A hydraulic rotary absorption brake comprises a disc 1 mounted on a shaft 3 connected to a rotary power source and a casing 5 around the disc supplied with liquid at an adjustable rate and provided with an outlet 12 of predetermined size. The casing 5 is carried by a hollow shaft 7 in bearings 9 and angular deflection of the casing is restricted by torque measuring means which may comprise a torsion member. Water or oil is supplied through the shaft 7 and thrown outwards by the disc 1 to form an annulus 13 extending radially inward over the radially outward part of the disc 1 to a depth inversely proportional to the speed of the shaft 3 so that the torque absorbed at a given speed is proportional to the rate of supply of liquid at the inlet 11. Liquid overflows at 15 at the upper limit of torque for a particular speed and unstable conditions occur if the annulus 13 fails to cover the outer part of the disc 1. The range of torque that can be absorbed by the brake is increased in the embodiments of Figs. 2, 3, (not shown) by providing a series of discs of increasing diameter each in a separate compartment of the casing overflowing into the next at different radii. In the embodiment of Fig. 4 the casing 52 has four outlets 54 to 57 at different radial distances from the shaft 50, communicating through conduits 58 to 61 with valves 52 to 65 discharging into a trough 66. If all the valves are open, the number through which liquid is discharging is an indication of the immersion of the disc and hence of the proportion of full load. To operate the brake over a reduced power range, a smaller disc is used and one or more of the valves 62 to 65 are closed in sequence. The form of disc shown is suitable for high shaft speeds.

Filed: 1970-07-01
Abstract: 1298270 Sonar; electro-acoustic transducers WESTINGHOUSE ELECTRIC CORP 1 July 1970 [9 July 1969] 31828/70 Headings H4D and H4J] A side looking sonar apparatus includes an elongated transducer means whose active surface is wider at one end thereof than in the centre. An array comprises narrow transducer elements 68 and wider elements 67 mounted on the arc of a circle whose radius equals the height of the array above the sea-bed. The elements are arranged such that their axes intersect at the maximum range on the line of focus F. The width of the elements 67 is such that they contribute substantially nothing to the energy received by the sea-bed at short ranges (around point n), thus simulating a short array giving high depth of focus. At long ranges (around point m) all the transducers are effective, thus providing a long array giving good resolution. The array may also be formed on a straight line (Fig. 16, not shown). The elements may be either piezoelectric or ceramic (e.g. barium titanate) or magneto-strictive. The received pulses are passed through a time varying gain amplifier to a magnetic tape, cathode ray tube or pen recorder. Fig. 2 not shown)).

Title: Memory
IPC: G11C11/44
Filed: 1962-08-20
Abstract: 980,938. Superconductive memory arrays. RADIO CORPORATION OF AMERICA. Aug. 20, 1962 [Aug. 30, 1961; May 17, 1962], No. 31905/62. Heading H3B. In a memory device in which a storage plane 30 shields the magnetic field produced in driving conductors 45, 48 except when a certain digit is stored therein, information is read out by the use of another conducting plane 32 beneath the storage plane 30 so that the two act as a transmission line and propagate an electromagnetic wave when a magnetic field is produced between the planes. In the embodiment described the storage plane 30 is superconducting so that only coincident drive currents above a certain amplitude will produce a field sufficient to drive the storage plane 30 resistive and allow the flux to pass through the plane at the normal areas shown in Fig. 2. This flux then induces currents in the superconducting part of the plane which store information. Currents of opposite polarity are used to write in the other binary digit. Read currents produce a field which penetrates the film and produces an output in line 50 if one digit is stored but the field will not penetrate if the other digit is stored, since in one case the circulating superconducting current is augmented and in the other diminished. A matrix is described (Fig. 8, not shown) using cryotron selection trees and having a number of output terminals arranged along the edges of the planes the outputs being added by means of transformers whose secondaries are connected in series. In an alternative method of read out the output is connected to the control conductor of a cryotron (Fig. 7). To reduce spurious outputs the drive conductors are arranged to be normal to the edges of the storage plane 30 at the edges. Alternatively the conducting plane 32 may be screened by a third plane connected to the storage plane on three sides. The conductors and planes may be formed by vacuum deposition on insulating layers of silicon monoxide. The end of the parallel transmission line opposite the output is terminated by a short circuit or an impedance of several ohms.

Abstract: 641,615. Automatic temperature control systems. BRITISH THERMOSTAT CO., Ltd. Dec. 3, 1947, No. 31944. [Class 38 (iv)] [Also in Group XXXVI] In a temperature control system employing a Wheatstone bridge circuit 1 the unbalanced output of which regulates a heater or cooler 9 to restore the temperature to a predetermined value, two supplementary or anticipatory temperature-sensitive resistances 11, 11a disposed in close relation, are connected in adjacent sides of the bridge so that they do not normally influence the balance. The resistance 11 responds directly to the surrounding temperature, whereas the resistance 11a is arranged to respond to this temperature only after a predetermined time lag. Thus, for air flowing in a duct 10 past the heater 9 to a chamber 3, the heater is initially controlled by the resistance 11 but after the time lag when the resistance of 11a becomes equal to that of 11 the control is passed to the main control element 2. An anticipatory effect may be obtained by placing the resistances 11, 11a before the heater (Fig. 2, not shown). The time lag of resistance 11a is made adjustable by variable vents in the shroud 12 of the resistance (Fig. 3, not shown), (see Group XXXVI).

Title: Method of manufacturing luminescent screens

Filed: 1972-07-07
Abstract: 1380186 Luminescent screens PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 7 July 1972 [10 July 1971] 31954/72 Heading C4S [Also in Division H1] A luminescent screen comprises a mosaic of luminescent areas 6 separated by transverse cracks 5 in the layer. The cracks are formed by differential thermal contraction of the luminescent coating 1 and substrate 2; for example caesium iodide may be evaporated on to a substrate maintained at 150-200 C. and having a higher thermal expansion coefficient so that cracks develop after gradual cooling. The average spacing between cracks depends on the thickness of the luminescent layer, so a thin layer may be deposited first to develop the required crack distribution, and further layers are deposited on top of the first layer to build up the required thickness; the cracks then extend into the further layers. Another method of initiating cracking at a desired spacing comprises impressing a gauge structure on the surface of the substrate to initiate the crack structure. The cracks in a screen may be filled with material which is impervious to light or which absorbs X-rays and exhibits collimation, the latter being used with input fibre optic or channel intensifier plates. A screen for X-rays may have a substrate of aluminium or titanium, or for soft X- rays beryllium may be used. If the screen carries a photo-cathode for producing an electron image an intermediate protective layer of aluminium oxide also for optimum electrical conductivity should be provided. In one example the input screen of an X-ray image intensifier tube comprises caesium iodide 200 microns thick with a crack frequency of 120-125 lines/cm. The display screen is also of caesium iodide and has a thickness of 5 microns and a crack frequency of 100 lines/mm. Multiple layers of different luminescent materials may be provided. Electron microscope, oscilloscope and T.V. display tubes, light intensifiers (e.g. infra-red) and gamma detectors are disclosed.
